Test I: The Driver Seat Module (DSM) Does Not Respond To The Diagnostic Tool

PINPOINT TEST I: THE DRIVER SEAT MODULE (DSM) DOES NOT RESPOND TO THE DIAGNOSTIC TOOL

Normal Operation
The DSM communicates with the diagnostic tool through the medium speed controller area network (CAN), circuits VDB06 (GY/OG) and VDB07 (VT/OG).

Check the medium speed CAN circuits VDB06 (GY/OG) and VDB07 (VT/OG) between the DSM C3299c and the data link connector (DLC) C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in one of the high speed CAN circuits, damage to the DLC C251, damage to the DSM C3299c, or a problem in an in-line connector.

Possible Causes
- medium speed CAN data plus circuit VDB06 (GY/OG) open
- medium speed CAN data minus circuit VDB07 (VT/OG) open
- DSM C3299c
- DSM
